  - addModelChangedListener
```
void addModelChangedListener(IModelChangedListener listener)
```
    Adds the listener to the list of listeners that will be notified on model changes.
    
    Parameters:
    
    listener - a model change listener to be added
  - fireModelChanged
```
void fireModelChanged(IModelChangedEvent event)
```
    Delivers change event to all the registered listeners.
    
    Parameters:
    
    event - a change event that will be passed to all the listeners
  - fireModelObjectChanged
```
void fireModelObjectChanged(Object object,
                            String property,
                            Object oldValue,
                            Object newValue)
```
    Notifies listeners that a property of a model object changed. This is a utility method that will create a model event and fire it.
    
    Parameters:
    
    object - an affected model object
    
    property - name of the property that has changed
    
    oldValue - the old value of the property
    
    newValue - the new value of the property
  - removeModelChangedListener
```
void removeModelChangedListener(IModelChangedListener listener)
```
    Takes the listener off the list of registered change listeners.
    
    Parameters:
    
    listener - a model change listener to be removed
